Rohde & Schwarz MXO3-K36 Frequency Response Analysis Option

Overview

The Rohde & Schwarz MXO3-K36 is a frequency response analysis (FRA) option for the MXO 3 series oscilloscope that characterizes the frequency response of electronic devices, passive filters, and amplifier circuits. It enables engineers to measure control loop response (CLR) and power supply rejection ratio (PSRR) with precision from 10 mHz to 50 MHz, providing valuable insights into device stability and performance.

Key Features

• Frequency range from 10 mHz to 50 MHz for comprehensive analysis
• Fixed or amplitude profile mode with configurable test points from 10 to 500 per decade
• Amplitude level range: 10 mV to 10 V into high impedance or 5 mV to 5 V into 50 ohms
• Integrated stimulus generation using the MXO3-B6 arbitrary waveform generator (prerequisite)
• Measurement result table with frequency, gain, and phase shift data
• Calibration optimization for accurate passive probe characterization
• Save and export capabilities for reporting and documentation

Analysis Capabilities

• Control loop response (CLR) characterization for closed-loop systems
• Power supply rejection ratio (PSRR) measurement in switch-mode supplies
• Logarithmic gain and phase response plotting
• Amplitude profile optimization to improve signal-to-noise ratio at different frequency ranges

Applications

• Passive filter design and characterization
• Amplifier circuit validation and optimization
• Switch-mode power supply (SMPS) stability analysis
• Frequency-dependent device behavior assessment
• Control system loop stability verification
